Proprietary Grade: NDEVACID™ DCO
Used primarily in the manufacture of fast-drying alkyd resins, paints, surface coatings, printing inks, primers, varnishes and polyamide resins. Typical (informational) fatty-acid composition: saturated acids ≤4.5%, unsaturated acids ≥90%, of which conjugated (diene) fatty acids typically ≥60% by UV/GC — reported for information, not as a numeric release specification.
Tested and certified in our laboratory according to official AOCS, ISO, ASTM, BP, USP, and EP compendial methods.
